CCR8 ( IC50 = 1.8 μM ); 5-HT1A ( IC50 = 5.4 μM ); 5-HT2B ( IC50 = 4.4 μM ); 5-HT2C ( IC50 = 34.8 μM ); 5-HT5A ( IC50 = 16 μM ); 5-HT6 ( IC50 = 5.9 μM ); α2A ( IC50 < 20 μM )

ZK 756326 prevents the CCR8 ligand I-309 (CCL1) from binding, with an IC50 value of 1.8 μM. ZK 756326 is a full agonist of CCR8, which cross-desensitizes the receptor's response to CCL1 and dose-responsively increases intracellular calcium. Extracellular acidification is stimulated in human CCR8-expressing cells by ZK 756326. To find out if ZK 756326's interaction is unique to CCR8, binding competition tests are run on a number of other G-protein-coupled receptors. In these tests, the inhibitory effect of ZK 756326 at 50 μM on radiolabeled ligand binding is examined. ZK 756326 exhibits >28 fold specificity for CCR8 at this concentration when compared to 26 other GPCRs, all of which have IC50 values greater than 50 μM. ZK 756326 exhibits reduced selectivity when tested against the adrenergic receptor α2A, the serotonergic receptors 5-HT1A, 5-HT2B, 5-HT2C, 5-HT5A, and 5-HT6, with IC50 values of 5.4, 4,4, 34.8, 16, 5.9, and <20 μM (at 20 μM 65% inhibition), respectively. Since the compound does not exhibit any agonist activity in a GTPγS binding assay when tested at concentrations up to 10 μM on the representative receptor 5-HT1A, it is unlikely to be an agonist on these biogenic amine receptors[1].

| Cell Assay |
U87 MG cells that express CCR8 are plated at a density of 10,000 cells per well on black 96-well plates coated with poly-D-lysine and cultured for an entire night. After that, cells are loaded with Calcium 3, a Ca2+-sensitive non-wash fluorescence dye, and allowed to sit in Hanks' balanced salts solution (which contains 2.5 mM probenecid, 3.2 mM CaCl22, 1% (v/v) fetal bovine serum, and 20 mM HEPES) for 60 minutes at 37°C. Fluorometric Imaging Plate Reader (FLIPR 3) is used to measure intracellular free-Ca2+ concentration changes as soon as the agonist is added at room temperature. In cross-desensitization experiments, the agonist (CCL1 at 30 nM or ZK 756326 at 3 μM) is added once, and then 100 nM CCL1 is added right away after[1].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.75 mg/mL (6.40 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 27.5 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.75 mg/mL (6.40 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 27.5 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
